The test failures seen in the following WK1 run were consistently failing on ToT WK1 until they were rebaselined last night, but the failures were still triggering retries in spite of our new results database checks. https://ews-build.webkit.org/#/builders/73/builds/20801 https://results.webkit.org/?suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fcss%2Fcss-cascade%2Fall-prop-initial-xml.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fgeolocation-API%2FPositionOptions.https.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fgeolocation-API%2Fpermission.https.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fweb-animations%2Fanimation-model%2Fanimation-types%2Faccumulation-per-property-002.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fweb-animations%2Fanimation-model%2Fanimation-types%2Faddition-per-property-002.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fweb-animations%2Fanimation-model%2Fanimation-types%2Finterpolation-per-property-002.html The issue might be that when we query the results database to analyze failures, we are only checking for platform (macOS/iOS) and configuration (release/debug), which will return results from both WK1 and WK2 and throw off the pass/fail percentage. Checking Results database for failing tests.
